## Resource

In this episode, Lucas and Luna dive into the opening days of the siege of Tenochtitlan in May 1521. They examine Cortés's strategy of cutting off the city's water supply from Chapultepec, the devastating impact of the brigantines on the lake, and the fierce resistance led by Cuauhtémoc. The conversation highlights the role of Tlaxcalan allies, the use of cannons and crossbows, and the gradual encirclement of the Aztec capital. Drawing on Bernal Díaz del Castillo's firsthand account and the Florentine Codex, they explore a moment of high tension: the failed assault on the Tacuba causeway, where the Spanish suffered heavy losses. The episode also touches on the psychological warfare of the Spanish, including the destruction of temples and the relentless pressure on Tenochtitlan's defenders.
